## What it is
Visual Event is a bookmarklet that visually overlays the JavaScript event handlers attached to elements on a web page, showing which elements will trigger actions when interacted with. It is a browser-based debugging aid for web developers from SpryMedia, the makers of DataTables.

## Use cases
- find which elements on a page have javascript event handlers attached
- debug why clicking an element does not trigger an action
- inspect event listeners added by libraries like jquery
- visually map event bindings across a complex web page
- understand legacy javascript code by seeing its event wiring

## When to choose
- you need a quick, zero-install way to see event handlers on any web page
- you are debugging event-driven front-end code in the browser
- you work with older jquery-era codebases where events are attached dynamically

## When to avoid
- you need full devtools-grade debugging with breakpoints and call stacks
- you only target modern frameworks where devtools already surface listeners
- you need an actively maintained tool with recent updates and a license

- artifact type: plugin
